## History

During the first Spanish missionary efforts on Guam, Malesso' was the site of resistance encouraged by Choco, a Chinese resident of the village. The parish of Malesso' was the second established by the Spanish on Guam. A large population of Chamorros from the Mariana Islands were relocated to the village during Spanish rule.
The village covers an area of 6 square miles (16 km$^2$) and is located on the shore below the volcanic hills of southern Guam. Places of interest for visitors include Merizo Bell Tower, Malesso' Kombento and Merizo Pier where ferries can be taken to Cocos Island (Guam) Resort. Several popular dive sites are located off the Malesso' coast.
In August 2021, Gov. Lou Leon Guerrero signed a bill officially changing the name of the village from Merizo to Malesso'.

### Contamination of lagoon

Officials from the Guam Environmental Protection Agency, Department of Public Health and Social Services and the Coast Guard announced findings of major polychlorinated biphenyl (PCB) contamination in the Cocos Lagoon on February 20, 2006 and warned people not to eat fish caught there. The contamination is believed to have come from a United States Coast Guard station which operated on Cocos Island from 1944-1963.
